Ceruminous gland tumours are uncommon in the dog and this paper reports a case of two such tumours which arose in either ear of a 12 year old male long-haired Dachshund. Histologically, one tumour was a ceruminous adenoma and the other a rare ceruminous mixed tumour of borderline malignancy. 相似文献

This paper reports the effects of prolonged stilbestrol administration in ovariectomized female dogs and some observations on the effects of this hormone on a group of male dogs. It was shown previously that ovarian tumors, which frequently metastasise to serous surfaces, can be produced in dogs by prolonged administration of stilbestrol. Total amounts of stilbestrol given to individual dogs in this study ranged from 180 to 570 mg, mainly over a period of 48 weeks. The ability of non-ovarian serous surfaces to proliferate in response to stilbestrol, independently of ovarian metastases, was studied in 5 females and 4 males. Papillary proliferations occurred on the uterine serosae in 3 females and on the testicular and epididymal serosae in 2 males. In no case was there papillary proliferation on serous membranes of non-genital organs. One of 2 entire females given stilbestrol had proliferations regarded as metastases of ovarian origin on non-genital serous membrane. In addition to ovarian changes, stilbestrol can cause primary proliferative lesions in the serous membranes of certain genital organs in both sexes. There is no evidence that serous membranes of non-genital organs be capable of a primary proliferative response to stilbestrol. 相似文献
